Rstudio crashes on loading library(staplr)

[adpadi]

I wasn't able to load staplr successfully in Rstudio. It would crash. I then tried running the R script I had written in Rgui and everything worked fine. My issue is resolved because of that, but I wanted to let you know it's crashing in Rstudio. Also in case anyone else comes across this issue you can try to run the script outside of Rstudio.

I also tried library(staplr) and this command crashes Rstudio.

Could you try

Just

rJava::.jinit()

and ideally on a separate session

pdftk_jar <- system.file('pdftk-java/pdftk.jar', package = 'staplr', mustWork = TRUE)
rJava::.jpackage('staplr', morePaths = pdftk_jar, lib.loc = .libPaths()[1])
jv <- rJava::.jcall("java/lang/System", "S", "getProperty", "java.runtime.version")
if(substr(jv, 1L, 2L) == "1.") {
    jvn <- as.numeric(paste0(strsplit(jv, "[.]")[[1L]][1:2], collapse = "."))
    if(jvn < 1.8) stop("Java >= 8 is needed for staplr but it is not available")
}

and see if/when it crashes? the .libPaths()[1] is meant to be where staplr is installed
